Public Member Functions | |
virtual | ~BluetoothA2DPCommon ()=default |
Destructor. | |
void | set_auto_reconnect (bool active) |
activate / deactivate the automatic reconnection to the last address (per default this is on) | |
virtual void | disconnect () |
Closes the connection. | |
virtual void | end (bool releaseMemory=false) |
Closes the connection and stops A2DP. | |
virtual bool | is_connected ()=0 |
Checks if A2DP is connected. | |
virtual void | set_volume (uint8_t volume)=0 |
Changes the volume (use the range 0-100) | |
virtual int | get_volume ()=0 |
Determines the volume. | |
virtual void | set_volume_control (VolumeControl *ptr) |
you can define a custom VolumeControl implementation | |
virtual esp_a2d_audio_state_t | get_audio_state () |
Determine the actual audio state. | |
virtual esp_a2d_connection_state_t | get_connection_state () |
Determine the connection state. | |
virtual void | set_on_connection_state_changed (void(*callBack)(esp_a2d_connection_state_t state, void *), void *obj=nullptr) |
Set the callback that is called when the connection state is changed. | |
virtual void | set_on_audio_state_changed (void(*callBack)(esp_a2d_audio_state_t state, void *), void *obj=nullptr) |
Set the callback that is called when the audio state is changed. | |
virtual void | debounce (void(*cb)(void), int ms) |
Prevents that the same method is executed multiple times within the indicated time limit. | |
void | log_free_heap () |
Logs the free heap. | |
const char * | to_str (esp_a2d_connection_state_t state) |
converts esp_a2d_connection_state_t to a string | |
const char * | to_str (esp_a2d_audio_state_t state) |
converts a esp_a2d_audio_state_t to a string | |
const char * | to_str (esp_bd_addr_t bda) |
converts a esp_bd_addr_t to a string - the string is 18 characters long! | |
void | set_task_priority (UBaseType_t priority) |
defines the task priority (the default value is configMAX_PRIORITIES - 3) | |
Protected Member Functions | |
